How Does Duct Silencer Work

With the silencer in place the pressurized gas behind the bullet has a big space to expand into.

How does duct silencer work.

For projects that necessitate silencers that are larger than the maximum standard dimensions 48 x 48 we carry rectangular duct silencers. The duct extension should slip onto the silencer component 2 or until the lock forms butt together. When the bullet finally exits through the hole in the silencer the pressure. Do not use any fasteners at this time as some movement may be needed to align the components see figure 1 2.

Conic flow tubular silencers are available for silencer applications including low frequency silencers having acoustic performance specifically engineered for the 63 hz 125 hz and 250 hz octave bands. These can be fabricated as two separate standard silencers and constructed to fit the structure you are working with. How do the duct silencers work. A duct silencer can be engineered specifically for use in clean environments such as hospitals.

The combined interior diffuser cone and exterior square. The size can differ depending on the frequency of the sound being controlled. As the silencer contains air pockets this can help to trap the air inside the silencers. Low frequency silencers are engineered specifically for 63hz and similar octave bands.

The basic principle is to transform the round cross section of the duct into a slim rectangular one while maintaining the area of the cross section because my intuition told me that reducing the duct size will make my a c less efficient and ultimately perhaps even damage it. A silencer screws on to the end of the barrel and has a huge volume compared to the barrel 20 or 30 times greater. But it s also possible to have silencers that don t have any filling. The linings in the silencer don t shed particles into the air.

When assembling larger silencer components it may be easier to slip the duct extension on with the inlet or outlet facing upwards. The way duct silencers work is by trapping the sound waves that meet it allowing the waves to fill the silencer located inside the fitting.
